JSB Knock Out Airgun Slugs .177/4.51 10.03gr /500

These little guys shoot into one hole at 20 meters out of my Weihrauch HW97k underlever springer. The point of aim dropped only one mildot (no lateral drift) compared to the JSB 10.34 grain Exact Heavies, my match (silhouette and springer benchrest) pellets.
I got the idea to try these slugs after watching Kyle on Airbros SA on Youtube stacking them pellet on pellet with a break-barrel Weihrauch. (Good shooting, good rifle, good ammo!)
Turns out that JSB slugs and Weihrauch springer rifling are a match!
